The utility model content
The purpose of this utility model is exactly in order to solve traditional pulse control instrument and line output shortcoming, provide a kind of have simple in structure, easy to use, the method of utilization matrix control, make and line output has become matrix form output, thereby significantly reduced the novel pulse control instrument based on matrix output of advantages such as the volume of pulse instrument and development cost.
For achieving the above object, the utility model adopts following technical scheme:
A kind of novel pulse control instrument based on matrix output, it comprises pulse control instrument, and pulse control instrument is provided with single-chip microcomputer, and single-chip microcomputer is connected with drive circuit, and the output of drive circuit is connected with m pulse valve control relay with n intake valve control relay respectively; Corresponding m pulse valve all is connected in described m pulse valve control relay and each air chamber, the normally closed switch of n intake valve control relay is connected with the intake valve of n air chamber, normal open switch then with n air chamber in m pulse valve being connected with each pulse valve control relay connect successively, thereby constitute the matrix type of attachment of m+2n.
Described each pulse valve control relay is the hilted broadsword relay, the 0V end of the public termination power of hilted broadsword relay.
Described each intake valve control relay is a dpdt relay, the public termination positive source of dpdt relay.
The utility model just output of pulse control instrument all is unified into relay output; M hilted broadsword relay used in the output of corresponding m pulse valve, and n dpdt relay used in the output of n intake valve; M hilted broadsword relay output of pulse instrument is received on m the pulse valve of all air chambers, one road normally closed switch output of n two keys relay is received on n the intake valve, often opening on all pulse valves that output is connected to air chamber successively of another road of all two keys relay, the common port of two keys relay all connects+the 24V power supply, the 0V end of the public termination 24V power supply of hilted broadsword relay.
Operation principle of the present utility model is as follows:
In the time of pulse control instrument work, two keys relay normally closed exported to intake valve to be provided+the 24V power supply, INO, when the needs pulse valve is jetted, hilted broadsword relay output 0V, the normally closed switch of two keys relay is according to opening from 1 to m order simultaneously, and another normal open switch provides+24V power supply and the digit pulse valve power supply of hilted broadsword relay formation closed-loop path according to the pulse valve of same orderly close-down for corresponding air chamber, makes the pulse valve of this air chamber work successively.
The beneficial effects of the utility model are: intake valve and the logical relation between the pulse valve according to air chamber are that each air chamber is only under the situation that intake valve cuts out, the characteristics that concern that the pulse valve of this air chamber could be jetted successively, design a kind of novel pulse control instrument, and line output be modified into matrix output, newly-designed pulse control instrument is by means of the advantage of relay, outside output has been increased logic, feasible output has only under the situation on (2n+m) road, reached the also effect on line output control (m+1) * n road, saved the development cost of pulse control instrument, and under the many more situation of total air chamber and pulse valve, the result of use of this utility model is obvious more.
The utility model is compared with the technology of existing pulse control instrument, under large numbers of situations of the air chamber of needs control and pulse valve, can significantly reduce the volume and the development cost of controller.
